Need some help here in NZ - 986 Heater

[Winckel]

Hey Guys,

I’m all the way down under in New Zealand.

I really like the Tech Articles on your website, These have been very useful.

I purchased my Boxster in the middle of summer & did not really use the heater.

Now it teases me with the faintest amount of heat output....

I am a VW Technician by trade so I have some experience 

I have drained the coolant & flushed the heater core...appears to be flowing fine, Bled the system & checked in & out hose to the core with thermometer & these are sitting right on 85 degrees (unsure what this would be in Farinheight)

Also my car is RHD...So under the LH (passengers) side of the dash is what appears to be the blender motor. I have checked the operation of this & also disconnected & manually moved it with the same result....a faint warm heater.

Engine also runs smack bang in the middle of the temp gauge & gets up to temp within 6KM so thermostat appears fine.

Is there something I should know as I am seriously tempted to sell the vehicle now as it is getting to me!

So you are getting air flow in normal amounts? You have the vents selected via the 3 horizontal buttons on the HVAC controls? The temp set well above your outside temp?

[Winckel]

yes.

You might have air pockets inside your heater core.
Check again to make sure.

I have the same problem but when I get on the highway it starts blowing warmer air. its not that cold yet so its not that big of a problem but It will get colder soon. My temp is normal so I assume the thermostat is good. I had a BMW that was doing the same and it turned out to be a valve that opened to allow water to the heater core, does the boxter have such a valve?
